Real-Time Earthquake Warnings Now Active in California

Stay Prepared with California's Advanced Warning System

On Monday, October 3, 2022, California activated its statewide earthquake warning system, giving residents precious seconds to prepare for potential ground shaking.

How It Works

Ground Motion Sensors

The system relies on ground motion sensors strategically placed across the state. When these sensors detect seismic activity, they send real-time data to a central processing center.

Early Warnings

The processing center analyzes the data to determine the magnitude and location of the potential earthquake. If the event meets certain thresholds, an early warning alert is issued within seconds.

Notification

Alerts are sent to smartphones, televisions, and radios via the MyShake app and other notification channels.

What to Do When You Receive an Alert

• Stay calm and follow the instructions.
• Drop to the ground, take cover under a sturdy table or desk, and hold on.
• Stay away from windows, glass, and outside walls.
• If you are driving, pull over to the side of the road and stop.

Background

California has experienced several major earthquakes in recent history, including the 1906 San Francisco earthquake and the 1989 Loma Prieta earthquake.

The state has invested heavily in earthquake preparedness, including the installation of early warning systems like ShakeAlert.

Conclusion

California's statewide earthquake warning system is a significant step forward in protecting residents from the devastating effects of earthquakes.

By providing early warnings, the system gives people valuable time to take precautionary measures and reduce the risk of injury and damage.
